I've build a website that will be going live soon and just have a couple questions about preventing SQL injection, I understand how to use mysqli_real_escape_string but I'm just wondering if I have...
I am very new to the whole PHP/MSSQL coding and need assistance with SQL Injection prevention. I am adding a simple search feature to a website that uses a MSSQL database. The code works as I want...

I want to know is there any other way to prevent SQL-injection in PHP-8? I see these methods are for PHP 5 and PHP 7 to prevent SQL injection. but what should we do in PHP 8?
In PHP, I've found a few methods to prevent Sql Injection. Binding parameters is one of them. But I'm unable to find a complete explanation of how binding parameters actually prevent Sql Injection....
I heard people said : "The protection comes from using bound parameters, not from using prepared statement". May I know what is bound parameters? Bind_param is bound parameter? If yes, then the normal and simple PDO Prepared statement without Bind_param CANNOT fully prevent SQL injection?
For SQL injection - use bound variables as described in How can I prevent SQL injection in PHP? (it talks about prepared statements, but it is the binding that gives you protection, not the preparation). For XSS - if you are writing into HTML at point where either HTML or text is specified.
As for preventing SQL injection in it self, all you need is to use prepared statements. You can still clean or sanitize your data if there are some kind of values you don't want sitting in your tables - but that's kind of another discussion.
